HIV-1 is more virulent and more infective than HIV-2, [20] and is the cause of the majority of HIV infections globally. The lower ...
HIV can survive at room temperature outside the body for hours if dry (provided that initial concentrations are high), [31] and for weeks if wet (in used syringes/needles). [32] However, the amounts typically present in bodily fluids do not survive nearly as long outside the body—generally no more than a few minutes if dry. [23]

It is an approach for use in resource limited settings and is widely used in Africa and Asia and has been a useful research tool in studies of progression to ...
People living with HIV can expect to live a nearly normal life span if able to achieve durable viral suppression on combination antiretroviral therapy. However this requires lifelong medication and will still have higher rates of cardiovascular, kidney, liver and neurologic disease. [130] This has prompted further research towards a cure for HIV.
